使用说明

1. 运行程序后，点击"选择 Markdown 文件"按钮选择要转换的.md文件
2. 文件内容将显示在预览框中
3. 点击"转换为 DOCX"按钮选择保存位置并开始转换
4. 转换过程中会显示进度条和状态信息
5. 转换完成后会弹出提示框

依赖安装

在运行此程序前，需要安装以下依赖：

pip install PyQt5 markdown python-docx beautifulsoup4

功能扩展建议

1. 可以添加批量转换功能
2. 可以增加对更多Markdown扩展语法的支持
3. 可以添加主题切换功能
4. 可以增加转换历史记录功能

这个工具提供了美观的界面和完整的Markdown到DOCX转换功能，支持表格、代码块等复杂元素的转换，并提供了实时预览和进度显示。
